The present invention provides compositions for use in the treatment of long- established type 1 diabetes (TID) using peptides and analogs of heat shock protein 60 (Hsp60). The invention is exemplified using DiaPep277, a peptide analog of human Hsp60, which is shown to induce increase in plasma C-peptide and regeneration of islet beta cells. The invention further relates to regimens useful for treatment of long established TID in patients having no demonstrable islet beta cell-function.

Peptides of human heat shock protein of 60 kDa, that constitute epitopes for T cells, as well as their derived peptides, which are modified at the contact sites with the MHC molecule, are useful to induce mechanisms of peripheral tolerance, in particular mechanisms of anergy or mediated by clones of regulatory T cells in patients with Rheumatoid Arthritis. The invention also refers pharmaceutical compositions comprising such peptides for the treatment of Rheumatoid Arthritis.

The present invention is related to a method of treating a T cell-mediated inflammatory autoimmune disease by administering to an individual in need thereof an immunogenic composition comprising a recombinant construct of a nucleic acid sequence encoding heat shock protein 60 (HSP60), or an active fragment thereof, wherein the nucleic acid sequence is operatively linked to one or more transcription control sequences, and wherein the disease is other than insulin dependent diabetes mellitus (IDDM), thereby treating the disease.

The present invention relates to a detection chip for performing gene detection to various vibrio and its detection and applications. The invention provides 16S rRNA sequences corresponding to each vibrio of vibrio anguillarum, vibrio harveyi, vibrio alginolyticus, vibrio parahaemolyticus, brilliant vibrio and Fisher vibrio; heat shock protein hsp60 probe sequence; virulence gene probe sequence; 16S rRNA forward primer sequence; 16S rRNA reverse primer sequence; heat shock protein hsp60 forward primer sequence; heat shock protein hsp60 reverse primer sequence; virulence gene forward primer sequence and virulence gene reverse primer sequence. The present invention has specific, sensitive and high-throughput features, can simultaneously detect six kinds of bacteria virulence genes, and the invention will effectively guide the production as an important disease early-warning detection method used in clinical diagnosis of aquatic animals.

The invention belongs to the field of biological detection, in particular to a protein antigen composition for detecting an Alzheimer's disease autoantibody in a human serum sample and an applicationof the composition. The adopted technical scheme includes that the antigen composition comprises at least two protein fragments of the following proteins: MAPT, ADARB1, HSP60, P21, DAG, DNAJC8, RAGE,ASXL1 and JMJD2D. Based on the above antigen composition, a kit for diagnosis, especially early diagnosis of Alzheimer's disease or related risks can be prepared. By using the antigen composition, early Alzheimer's disease can be diagnosed pertinently, rapidly and accurately, and thus the composition has important practical significance.

The present invention provides improved vaccines comprising an isolated viral antigenic peptide and a synthetic peptide derived from a T cell epitope of HSP60. The invention includes mixtures where the peptide serves as an adjuvant as well as conjugates where the peptide is covalently linked to the viral antigen. The known synthetic peptide carrier, p458, provides significantly improved immunogenicity for synthetic viral epitopes and analogs. Ec27 is a novel peptide derived from HSP60 which increases the immunogenicity substantially of the viral antigen both as a mixture or a covalent conjugate. Some of the isolated viral epitopes are novel and are claimed for diagnostic as well as therapeutic or prophylactic uses.
